Disease-predisposing germline mutations in cancer susceptibility genes may consist of large genomic rearrangements that are challenging to detect and characterize using standard PCR-based mutation screening methods. Here, we describe a custom-made zoom-in microarray comparative genomic hybridization (CGH) platform of 60mer oligonucleotides. The 4 x 44 K array format provides high-resolution covera
Blue diode lasers emitting 5 mW continuous-wave power around 400 nm have recently become available. We report on the use of a blue diode laser together with a 30 mW red diode laser for sum-frequency generation around 254 nm. The ultraviolet power is estimated to be 0.9 nW, and 35 GHz mode-hop-free tuning range is achieved. This is enough to perform high-resolution ultraviolet spectroscopy of mercu
The neurobiological bases of mood disorders remain elusive but both monoamines and neuropeptides may play important roles. The neuropeptide cocaine and amphetamine regulated transcript (CART) was shown to induce anxiety-like behavior in rodents, and mutations in the human CART gene are associated with depression and anxiety. We measured CART-like immunoreactivity (-LI) in genetic rat models of dep
Despite improved treatment results of childhood acute lymphoblastic leukemia (ALL), 20% to 30% have a relapse, and then the outcome is very poor. We studied 40 children with ALL marrow relapse piloting an ALL relapse protocol with well-known drugs and drug combinations by using a concept of response-guided design. We also measured response in logarithmic fashion. Our primary end points were achiev
CD40 is a costimulatory protein expressed on the surface of many different cells. It delivers signals regulating diverse cellular responses, including proliferation, differentiation, growth suppression, and cell death. In this study, we report a novel CD40 mutant (c.234C>A or p.H78Q) that is expressed in the U266 cell line and in freshly isolated tumor cells. Three-dimensional structural model and
Complications of dopamine replacement for Parkinson's disease (PD) can limit therapeutic options, leading to interest in identifying novel pathways that can be exploited to improve treatment. p11 (S100A10) is a cellular scaffold protein that binds to and potentiates the activity of various ion channels and neurotransmitter receptors. We have previously reported that p11 can influence ventral stria
Transplants of fetal dopamine neurons can be used to restore dopamine neurotransmission in animal models of Parkinson's disease, as well as in patients with advanced Parkinson's disease. In these studies the cells are placed in the striatum rather than in the substantia nigra where they normally reside, which may limit their ability to achieve full restoration of motor function. Using a microtrans
Previous studies have shown that serotonin neurons play an important role in the induction and maintenance of l-DOPA-induced dyskinesia in animals with lesion of the nigrostriatal dopamine system. Patients with Parkinson's disease that receive transplants of foetal ventral mesencephalic tissue, the graft cell preparation is likely to contain, in addition to dopamine neurons, serotonin neurons that

The blood loss-reducing effect of desmopressin during dextran therapy was studied in a double-blind fashion in 79 elderly but otherwise healthy patients with preoperative normal bleeding time undergoing total hip replacement for primary coxarthrosis. An infusion of desmopressin (0.3 microgram/kg body weight) or placebo was randomly administered immediately after administration of spinal anaesthesi
In a 1992 questionnaire study, we found that certain nasal symptoms and symptom-provoking factors were associated with prevalence of self-reported chronic bronchitis/emphysema (CBE). In this follow-up study, we examined whether any nasal features could predict an increased incidence of self-reported physician's diagnosis of CBE/chronic obstructive pulmonary disease (COPD). In 2000, a survey was pe
Objective To examine children's competence while cycling, as demonstrated in mistakes in performance and failure to comply with safety rules. Methods Children in three age groups (8, 10, and 12 years) participated in a realistic yet simulated traffic environment. Results The boys' cycling speed increased steadily with age, while that of the girls increased from 8 to 10 but decreased at age 12. Mos
This is the lecture that I gave when I was awarded Acta Ophthalmologica's gold medal and honorary award at the Nordic Ophthalmological Congress in Reykjavik in August 2010. I was inspired by Jared Diamond's famous book: Guns, Germs, and Steel, The Fates of Human Societies. Diamond is professor of geography and physiology at the University of California, Los Angeles. In this book, which won the Pul
Objective Our aim was to study depression and anxiety in atrial fibrillation (AF) patients as risk factors for all-cause mortality in a primary care setting. Methods The study population included adults (n = 12 283) of 45 years and older diagnosed with AF in 75 primary care centres in Sweden. The association between depression or anxiety and all-cause mortality was explored using Cox regression an
Abstract in UndeterminedFlow-induced oscillation of an elastically supported circular cylinder subject to an incompressible fluid at Re=100 and 400 has been studied using three-dimensional simulations. The cylinder is either subjected to a uniform flow in an unconfined surrounding or confined by rectangular channel, i.e. the cylinder is confined in both the span-wise and the cross-stream direction
In this study, we determined the diagnostic accuracy of cerebrospinal fluid (CSF) biomarkers to predict development of Alzheimer's disease (AD) within five years in patients with mild cognitive impairment (MCI). To do so, the levels of tau, phosphorylated tau, Abeta42, Abeta40, Abeta38, sAbetaPPalpha, and sAbetaPPbeta were analyzed in 327 CSF samples obtained at baseline from patients with AD (n=
The kinetics of insulin, glucagon and somatostatin release was studied in human pancreatic islets. Batches of 10-15 islets were perifused and the hormones measured with RIA in 30-sec fractions. Increase of glucose from 3 to 20 mM resulted in a brief pulse of glucagon coinciding with suppression of basal insulin and somatostatin release. There was a subsequent drop of glucagon release concomitant w
OBJECTIVE: Prevalence and clinical relevance of patellofemoral (PF) osteoarthritis (OA) after anterior cruciate ligament (ACL) injury. METHOD: Prospectively we studied 94 out of 100 consecutive patients 15 years after acute ACL injury. ACL reconstructions were only performed late if recurrent "give way" persisted or a secondary meniscal injury suitable for repair occurred. The subjects, mean age 4
